Hi all,
Let me explain my requirement properly.
I have created a table using wickets component DefaultTableModel. Number of
rows in the table is dynamic. One of the column is radio button. This radio
button is used to select that particular row.
I used wickets fragment feature to implement this. My html has something
like this...
<div>
<table cellpadding="0" cellspacing="1" wicket:id="table"/>
</div>
<wicket:fragment wicket:id="radioButtonFrag">
<input type="radio" wicket:id="selected"/>
</wicket:fragment>
My Fragment is like this...
public class FlightSelectionFragment extends Fragment {
public FlightSelectionFragment(String id, String markupId,
MarkupContainer markupProvider, RadioGroup
radioGroup) {
super(id, markupId, markupProvider);
radioGroup.add(new Radio("selected", new Model("")));
add(radioGroup);
}
}
The exception that i get is
WicketMessage: Error attaching this container for rendering:
[MarkupContainer [Component id = table, page =
com.emirates.poc.web.flight.page.SearchPage, path =
0:table.DefaultDataTable, isVisible = true, isVersioned = true]]Root
cause:java.lang.IllegalArgumentException: A child with id 'selected' already
exists:.
It means i can only add one Radio button to the RadioGroup. As the Radio
component get's created at runtime, i cannot specify it's name in the java
and html. There must be a way to add multiple radio button to the
RadioGroup using fragment. The same thing works if i replace Radio with
checkbox component.
How to solve this issue?
